F=m+a i think that might be it im not so sure about it, just seeing if i could help you out.

How do I find displacement

almond37 [142]

The displacement is just the distance between the starting point and the
ending point, and you don't care about the route taken or the actual distance
covered along the way.

This can bite you sometimes. For example, some day you'll be given the
diameter of a circle, and you'll be asked for the displacement of an ant that
walks around the circle 17 times and finally stops at the same place it
started from. You might go to work calculating the circumference of the
circle and multiplying it by 17. But if you think about it first, you realize that
if the ant ends up at the place he started from, then his displacement is zero.

For each situation, identify when sound would travel faster and why?

Rudiy27

A. Outside on a summer day, there are less particles that the sound bounces off of (snow and wind absorb the sound)

B. Water, sound travels faster through denser objects. Water has a higher density than air.

C. High air pressure, sound moves faster through matter that is closer together. This can be said because sound can't travel through space. (There is no atmosphere and consistent particles in space for sound to go through)

D. A piece of steel, It's denser than wood and water.

E. 90% nitrogen and 10% helium, nitrogen is denser than helium so it will move faster

A 0.350 kg block at -27.5°C is added to 0.217 kg of water at 25.0°C. They come to equilibrium at 16.4°C. What is the specific he

Gekata [30.6K]

The specific heat capacity of the block is $508J/kg^{\circ}C$

Explanation:

As the block is placed into the water, heat energy is transferred from the water (which is at higher temperature) to the block (which is at lower temperature), until the block and the water are in thermal equilibrium (= same temperature).

Therefore, we can write:

$Q_{water}=Q_{block}$
